This page is accessible from the node page by clicking on the name of one of your data source devices.

It looks very much like the main page and the node page - showing a set of measurement points at the top - but it also includes a few new items.

This is a list of the measurements that are sourced from this device.

To view more details or to edit a single measurement, simply click on its name to be taken to the measurement page.

In some devices, you can add and edit measurement points. However in most the set of measurements is fixed and can not be changed.
